企业级重构：四层模块化架构 + RBAC授权 + 安全加固 + 颜色引擎/配方推演增强

架构
- 后端从 flat routes/ 重构为 modules/<domain>/ 模块化结构（8个模块）
- 四层架构：Route -> Service -> Repository -> Prisma
- 新增 shared/ 基础设施（AppError 异常体系、ALS 上下文、prom-client 指标）
- 前端 Toast/Skeleton/Alert 组件基建 + formulaService 模板

安全
- JWT 签名算法修复（HS256 用 createHmac 而非 createHash）
- 密码哈希 async scrypt + timingSafeEqual
- API Key 从 localStorage 迁移至服务端 runtime/config.json
- Helmet 安全头 + rate-limit 全局限流 100 req/min
- 全局 auth preHandler + RBAC + Ownership 中间件

颜色引擎
- 色匹配切换为 cube 粗筛 + CIEDE2000 精排
- PantoneColor 表 + 种子数据 + 搜索端点
- AI 配色 Prompt 注入成分库 colorant 列表

配方推演
- 本地优化引擎（同 category 替换 + 成本排序）
- baseFormulaId 支持 + Pareto 散点图

文档
- ADR-0003 四层架构、ADR-0004 RBAC 授权模型
- 更新 ADR-0001/0002
- api-reference.md（29端点）、project-overview.md

部署
- Dockerfile * 2 + nginx.conf + docker-compose.prod.yml
- 健康探针 + 优雅关闭 + pg_dump 备份脚本
- ESLint + Prettier + tsconfig strict
